GPT-5.6 Sol and Gemini 4 Argon uncover critical PHP flaw

openai's gpt-5.6 sol and google's gemini 4 argon identified a critical php vulnerability that could impact millions of websites globally. the discovery was made as part of openai's patch-the-planet initiative, which aims to address significant security issues. security firm wiz independently found the same flaws using its own platform alongside gpt-5.6 sol and gemini 4 argon. the ai models proved useful in developing exploits, building attack detection, and validating the patch. the fix was coordinated over two months with php developers, wiz, cloudflare, and us agencies. openai proposes this process as a repeatable framework for future ai-driven security discoveries.
